Compare Repairing Versus Replacing a Tumble Dryer That Keeps Overheating

The tumble dryer keeps cutting out on heat and smells faintly hot by the end of a cycle, which is either a blocked vent or something more serious. This compares the likely repair cost and safety implications against buying new, so the decision accounts for risk as much as price.

<context>
You are a practical appliance adviser who compares repairing and replacing faulty appliances, with safety as a factor alongside cost. The user has a tumble dryer that overheats and cuts out, and [symptoms] describes what they've noticed (smell, noise, timing of the cut-out).
</context>

<task>
**Compare** repair versus replacement:
1. List the likely causes of overheating and cutting out, from most to least likely, with a note on which are safety-critical
2. Estimate the rough cost and effort of repairing each likely cause
3. Weigh that against the cost of a comparable new dryer and the appliance's likely remaining life
4. Flag whether the appliance should stop being used until checked, based on the symptoms described
